CUTTING AND FOLDING MECHANISM FOR USE WITH WEB PRINTING MACHINES Filed Jan. 22, 1929 Q i! I INVENTORI ATT'Y Patented Mar. 22, 1932 UNITED STAIIES PATENT OFFICE LOUISA. SCHMIDT, OF BROOKLYN',NEW YORK; ASSIGNOR TO B... HOE & 00., INQ, OF

' NEWYORK, N. Y., A. CORPORATION OF NEW YORK curmme AND roLnIN nEc AN IsM For; use WITH WEB PRINTING MACHINES appli catibn filed .Tanuary 22, 1929., Serial No. 334,338;

I The presentfinvention relates to folders for web printing machines. Thesefolders are commonly made with two formers ar-' ranged side by side, over each of which, one-1 half widthwebs are "passed toreceive a first fold andare thence led tocutting and folding cylinders which cut the web or webs into sheets." These sheets .then receive a second fold as theyleave the folding cylinder and are passed on to a delivery mechanism.

When the entire productofthe press is to be combined to form a single complete product the webs that have passed over one former. are sometimes associated 'with'the' 5 webs that have passed over the other former By this means the combined product is cut atone time and the number-of pages in the product is limited by'the capacity of the cut 2 ting cylinder.

, With the invention disclosed herein, the product passing over each former is cut sepa rately and .thetwo products are then associated to form a complete product, which may be of twice the number of pages that would be possible if they were all cut together.'{

The especial object of theinvention is to provide a cutting and folding mechanism adapted to cut, fold anddeliver products that are too heavy to be satisfactorily cut by mechanism heretofore used. v Another object'of'the invention is to provide cutting and folding mechanism adapted to either separately cut, fold and deliver the product from webs coming from two formers, or to separately cutthem and thereafter associate, fold and pass the products on to a delivery as a c-ombinedproduct. I

It is also an object of the invention to provide a cutting and folding mechanism of generally improved construction, whereby the device willbe simple, durableand'inexpensive in'eonstruction, as Well as convenient, practical, serviceable and efiicient in its use. With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts, and in the and they are both out and folded together. Y

details of construction hereinafter described and claimed, it being understood that various changes in the precise embodiment of theinvention herein disclosed may be made within the scope of what is claimed without depart ingjfrom the spirit of the invention.

The accompanying drawing shows a per tion of a folder that is similar to those commonly used with web'printing machines but an additional cutting cylinder and a transfer cylinder are shown as the preferredembodiment of the invention.

Portions of the two formersover which the webs are led to receive the first fold, are: shown at 11 and 12, the usual bending rollers: being shown and designated 13, 13, 14, 14', and the nipping rollers15, 1'5, 16 and 16.

so. i

' Guide rollers are indicated at 17, 1 8 and 19," e

the cutting cylinders used for straight runs at 20 and 21, the folding cylinders at 22 and 23, the. foldingbff rollers at 24, 24', 25 and 25, and the delivery fan wheels at 26 and 2 7.

The cutting cylinder used when the webs from both formers are to be associated is in dicated at 28 and the transfer cylinder at 29.

The cutting cylinders each" have cutting knives and they are indicated at 31, 32fajnd 33. They also have collecting pin mechanisms indicated at 34, 35 and 36. i

Similar collecting pin mechanisms 37, '37, 38, 38, 39 and 39, arecarried by the folding cylinders 22 and 23, and by the transfer cyl inde r ,29, and folding blades 41, 41, 42 and 42 are carriedlby the folding cylinders. f It will be understood that means not shown are provided for driving the nipping rollers, the cutting, collecting and transfer cylinders, the folding-off rolls, and the fan wheels; also that the collecting pin mechanism. and the folding blades are operated in proper timed relation to the cylinders by wellknown means. In'operation, the web or webspassing over the former 11 are drawn therefromby the nipping rollers 15 and '15, they then pass around the guide roller 17 and between the 12 are drawn by nipping rollers 16 and 16',

pass between the cutting cylinder 21 and the folding cylinder 23, are cut, then folded by the blade 42 between the rollers 25 and 25, and pass to the delivery, forming a single section product.

For a collected product alternate sections of. the cut webs are carried around the cutting cylinder 21 and associated with the other secm tions as above described in connection with the webs from the former 11.

When it is desired to associate the product coming from the former 12 with that coming from the former 11, the web from the former 12 may be led as shown by the dotted line, around the nipping roller 16, the guide rollers 18 and 19, to and between the cutting cylinder 28 and the transfer cylinder 29, where it is cut by the blade 33, and the productthen taken by the pins 39, which carry it to the cylinder 22, where it is impaled on the pins 37 or 37 and then folded oil with the product coming from the former 11..

It willbe understood that-thepins 36 may be used to carry alternate cut sections around the cylinder 28 and associate them with the other sections cut from the web coming from the folder 12 in order to form a collected product and that the collected product can likewise be transferred to the folding cylinder 22.

' It is thus possibleto fold and pass to the delivery from the folding cylinder 22. a sin gle section product, va twosection collected product, a two section associated product, or a four section collected and associated product; or, the webs cominn from each former may be operated on by the folding cylinder.

below it and be delivered either as a single section product or as a two section collected product. v

What I claim is: a

1. In a folder for a web printing machine, a pair of formers,- a pair of delivery mechanisms, separate cutting and folding mechanisms located between each former and its delivery mechanism, and means for associating the products from both of the formers after they are cut, and folding them together and delivering them as a complete product.

2. In a folder for a webprinting machine, acutting cylinder, a folding cylinder and a delivery, adapted to receive webs, to cut them into sheets, to fold and to deliver said sheets, and a second cutting cylinder having a :co-

then associated with the product which comes from the other former and which is separately cut. I

4. In a folder for a web printing machine, a first cutting cylinderan ace-acting first folding cylinder, adapted to receive webs from a. first former, cut them into sheets,

fold and passthe cut sheets to a first delivery,

a secondcutting cylinder-and a co-acting second folding cylinder, adapted to receive webs from a second former, cut them into sheets, fold and pass the cut sheets to a second delivery,and a third cutting cylinder and a co-actingtransfer cylinder, adapted to receive webs from the second former, cut them into sheets and associate the cut sheets with those on the first foldin cylinder, whereby a combined product may if: passed to the first delivery.

5; In a folder fora web printing machine,

two formers, two delivery mechanisms and means including cutting, folding and transfer cylinders, whereby webs coming from one of the formers maybe cut, collected,

folded and passed on to its delivery mechanism, or the aforesaid websfmay be cut and collected and then associated with the product which comes from the other former and which is sefarately cut.

6. Ina older for a. web printing machine, two formers two delivery mechanisms, and means includin cutting, folding and transfer cylinders, W1

two section collected product, or a four section collected and associated product may be cut, folded and delivered, each section of the product bein cut separately.

7. In a folder means including cutting, folding and transfer, cylinders, whereby two single section products, or two two section collected prodacts, or a two section associated product, or a four section collected and associated product may be out, folded and delivered, each section of the product being cut separately.

In testimony whereof, I afiix my signature.
